The role of immunization in JE control and prevention in China.

The thumbnail in the upper right corner is cited from reference [1]. The bar indicates JE case numbers. The JE pandemic in China peaked during 1965–1977. JE incidence decreased significantly after the local government covered a large proportion of immunization costs. In 2008, the JE vaccine was included in the EPI by the central government, and JE immunization became free throughout China. Subsequently, JE has been controlled and the incidence remains at a low level. The arrow indicates the introduction of the P3 inactivated JE vaccine in 1968. The arrow indicates the point at which the SA 14-14-2 live-attenuated JE vaccine was licensed for use in China in 1988.
